You're getting a MIL because the DC Sports header eliminates the cat and I believe one O2 sensor. I would go on the Sentra forum and see where other people have purchased their sims from. All it takes is a little searching and you should have plenty of help on this as I'm sure many of our Sentra members have done this upgrade.
